The PC-A20 is a mid tower PC case from Lian Li. It comes with all of the luxury features we have come to expect from Lian Li, including the famous brushed aluminum finish, tool-less maintenance, noise dampening, removable drive cages, an extended PSU cage for oversized PSUs, and two case fans (one 140mm for intake and another for exhaust). Like all of Lian Li's full sized offerings, the PC-A20 does not include a power supply, allowing end users to select one themselves for the potential to utilize a much stronger or quieter machine depending on ones personal preferences. While it appears to preform similarly to other Lian-Li cases such as the PC-A6010, the PC-A20 is a larger case with room for many more external and internal drives, has a superior internal layout, and includes a door to dampen noise and mask external drives.
